Title:
*Acyclic directed mixed graphs for binary data*

Abstract:
Acyclic directed mixed graphs (ADMGs), also known as semi-Markov models, 
represent the conditional independence structure induced on an observed 
margin by a DAG model with latent variables. Ancestral graphs (without 
undirected edges) are a subclass of ADMGs. In this talk we first present 
a parametrization of these model for binary data. We then describe a 
maximum-likelihood fitting algorithm that may be used for scoring.
